Many residential heating oil tanks come equipped with a float gauge that provides a rough estimate of the tank's fullness. However, this method is not always accurate for measuring oil levels. While the float gauge may give you a general idea of how much oil is in the tank (unless it's not working due to sludge buildup or other issues), it's not reliable for determining the exact amount of heating oil you have. In such cases, the most precise way to manually measure the oil level is by using a long, clean stick. In this blog, we will cover different tank sizes and how much oil you have based on your measuring stick.
